Hi! 
 
From the following code, what does it mean if forward &nbsp;is null? 
 
Why does this func passes string “forward” 
request.getSession().getAttribute(&quot;forward&quot;); 
 
+++++++++++++++++++++++++ 
 
public ActionForward create(ActionMapping mapping, 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;ActionForm form, 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;HttpServletRequest request, 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;HttpServletResponse response) 
&nbsp; &nbsp; &nbsp; &nbsp; throws Exception { 
… 
… 
&nbsp; &nbsp; &nbsp; &nbsp; String forward = (String) request.getSession().getAttribute(&quot;forward&quot;); 
 
… 
… 
&nbsp; &nbsp; &nbsp; &nbsp;if (forward==null) 
&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return (mapping.findForward(Constants.RETURN_TO_VIEW)); 
&nbsp; &nbsp; &nbsp;else 
&nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return &nbsp;(mapping.findForward(forward));

(String) request.getSession().getAttribute(&quot;forward&quot;) returns null?

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.

(String) request.getSession().getAttribute(&quot;forward&quot;) returns null?

(String) request.getSession().getAttribute("forward") returns null?
